Peptidomimetics, or synthetic bioactive peptides, have been developed that mimic the biological functions of peptides and proteins but overcome many of these challenges and limitations. Further, due to their wide range of activity, synthetic feasibility and ease of handling, they have played a vital part in biological research. This column will discuss the potential application of these short chain oligomers in cosmetics and personal care.

This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.

Lab tests on sunscreens show it takes more energy to produce mild erythema on protected skin than unprotected skin. Yet the FDA questions the need for SPFs higher than 50. In response, two outdoor studies were conducted using commercial products to challenge standing premises and determine if there is a measurable difference in an SPF 100 and SPFs of 50 or less.

Ultraviolet and infrared exposure are sources of premature skin aging, characterized by solar elastosis and extracellular matrix degradation. Polygonum aviculare extract is a cathepsin G inhibitor, and is shown here to oppose photoaging and infra’aging by improving skin firmness and elasticity, in turn reducing the appearance of wrinkles.

Cosmetic means for achieving rejuvenated skin can be positioned according to intensity of action, skin renewal speed and some functioning details, thus: gommage, scrub, exfoliation and peel represent the four rejuvenation strategies. In some regions, peel refers to aggressive treatments requiring authorized operators such as dermatologists or medical doctors. Therefore, this column will discuss only the first three methods for a better skin glow.

Standards for organic or natural products are largely the same, although some pertain to “natural” while others do “organic.” Each program and seal is intended for a given region, which should be taken into account when targeting specified markets. Here, the author reviews the most recognized natural and organic certifiers and seals around the globe.

The use and application of emulsions and emulsion science are widespread through the personal care industry. Conventional methods for processing emulsions require significant quantities of energy and time, thus cold process emulsion technologies have gained popularity. These provide the means to reduce both the energy demand and timescale of manufacturing processes, as will be described here.

Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.

Formulators of natural personal care products have the same lament as Kermit the Frog—i.e., “It’s not easy being green.” So before proceeding into the ever-unpredictable product development process, claims must be established as to what the final product aims to fulfill—especially in order to direct efforts toward the desired “green” claim for sustainable, natural, organic, etc.
